I bought an At&t iPhone 4S tonight off Craigslist strictly for the purpose of going to Straight Talk. I'm a complete newb when it comes to the jailbreaking issue. Anyway, the phone I bought clearly has been jailbroken before because it has some different looking things on the phone than the default version. The guy I bought the phone from says he restored it but if he did, all these different things should be gone right? The phone should look like it does right out of the box, correct? My question is can the phone not be jailbroken but still have these different things left behind? Like a different looking keypad, a different looking app store, an app called Passbook installed, a totally different menu when emailing pictures. If the phone is still jailbroken, where is the Cydia app? Thanks for any help.
